IES: Illuminating Engineering Society of North America
IES, the Illuminating Engineering Society of North America, is a nonprofit organization that develops and publishes standards regarding lighting. Headquartered in New York City, United States, IES standards are in effect throughout all of North America with its nearly 8,000 members. Internationally, IES collaborates with the International Commission on Illumination to promote uniformity with the rest of the world. Standards from IES are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: [email protected] or 1-212-642-4980 or Request Proposal Price.
Below are IES's best-selling standards. To find additional standards, please use the search bar above.
ANSI/IES RP-8-25
Recommended Practice: Lighting Roadway and Parking Facilities
Intended Audience: Engineers, Designers, Manufacturers, Municipalities, End Users, DOTs, Architects, Utilities, Environmentalists, Regulatory Groups, Energy Groups, Rdwy Maint. Orgs, Electrical Contractors, General Public. Intended Interest Categories: Specifier (US), Affected (UA), Public Interest (UP), Academic, Research (GAR), Government, Regulatory (GGR), General SME (GSME), Organizational (OM). Description: This Recommended Practice is a compilation of lighting design techniques and criteria, all offered for quality roadway lighting solutions.
ANSI/IES RP-7-21
Recommended Practice: Lighting Industrial Facilities (Includes Errata 1)
The primary purpose of this standard is to serve as a guide and educational tool for the design of permanently installed lighting systems for industrial facilities. This Recommended Practice deals entirely with lighting and does not give advice on the construction of a facility. The scope of this practice covers the design of new indoor and outdoor lighting systems for new industrial facilities as well as the redesign of lighting systems in existing industrial facilities. Recommendations are based on quality lighting practices, including: the safe movement of vehicles and people, enhancing the productivity and comfort of employees, conserving energy, and minimizing maintenance. Recommended minimum maintained lighting levels and maximum uniformity ratio guidelines are provided but are subject to variation for special circumstances when based upon sound engineering judgment. (Includes errata.)

IES G-1-22
Guide for Security Lighting for People, Property, and Critical Infrastructure
This publication includes specific sections dealing with critical infrastructure and homeland security. In addition, its authors have incorporated throughout the document many of the lessons learned and applied by these agencies. This document is intended to provide specific guidelines for situations where it has been determined that security is an issue (refer to Section 2.1) and is an important determining factor in the design or retrofit of a given property.

ANSI/IES LM-80-20
Approved Method: Measuring Luminous Flux and Color Maintenance of LED Packages, Arrays, and Modules
LEDs typically exhibit very long operational life characteristics and, depending on drive current and use conditions, can be in use for 50,000 hours or longer.The light output from LEDs slowly decreases over time. This characteristic of declining output without sudden and permanent failure creates a risk that an LED-based lighting product near end of life may be operating but performing outside the product’s specification, or outside required codes, standard practices, or regulations. LEDs may also undergo gradual shifts in the emitted spectrum over time that may result in unacceptable appearance or color rendering, or degraded efficacy. This Approved Method describes the procedures by which LEDs are tested for luminous (or radiant, or photon) flux maintenance, and chromaticity maintenance or wavelength changes over time when operated under controlled environmental and operational conditions. The resulting measurements may be used for comparison of LEDs, and they may be utilized in models that project long-term changes in light output during the life of the LEDs.
